Mobo that supports three PCI-E video cards?

[syukton]

Right now I run a pair of 7800GTX cards non-SLI, with one card driving my Dell 2407WFP and the other card driving two Dell 2005FPW's. In the near future I want to run a pair of 8800GTX cards in SLI driving my main screen and a single 7800GTX driving the other two. Is there a mobo out there that will support this? I see a lot of boards advertised with a third PCI-E x16 slot for a physics accelerator card, but I'm not sure that a video card would work in that slot just as well. Is there any sort of BIOS limitation I should be aware of?

I don't care either way WRT Intel or AMD, just as long as the chipset supports SLI and the board is a stable overclocker.

Thanks for your help.

Well i have this motherboard

http://www.asus.com/products4.aspx?modelmenu=2&model=1439&l1=3&l2=11&l3=397&l4=0

and the specs are:

2 x PCI Express x16 slot, support NVIDIA® SLI™ technology, at full x16, x16 speed(blue)
1 x PCI Express x16, at x8 speed(middle)
1 x PCI Express x1
2 x PCI 2.2


So, from what i understand, what you want will work.

I dont have all the cards you do otherwise i would test it.

There are three PCI-Express x16 slots on the board – the third slot is a new addition to NVIDIA’s nForce 600-series chipset and unlike the two ‘primary’ PCI-Express x16 slots, it only runs with an x8 electrical interface.

NVIDIA expects enthusiasts to install a third video card for physics acceleration in the future, but it will also allow users to install another PCI-Express x16-compatible expansion card like a dedicated RAID controller.

Again, i think you can do what you want.

I think the 680i is the only board with 3 PCI-E slots with SLI technology.
